Electron-Ion Ionization

  • Chapter

Abstract

Electron impact ionization of ions received little attention until the 1950’s when nonequilibrium approaches to astrophysics gained favor and the international push for controlled thermonuclear fusion began. Spurred by these needs, discussed more fully in Chapter 9, and aided by technological advances in ultra-high vacuum and electronics, Dolder, Harrison and Thoneman (1961) made the first successful electron-ion ionization measurements on e + He+ → He2+ + 2e. Not only was this the first ever measurement of this type, but it has served as a role model of the crossed charged beams technique and of quality work for the dozens of subsequent beams experiments.
